BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an elevated floor, in particular, to a side-folded type elevated floor.

2. Description of Related Art

Some factories and computer rooms may be provided with elevated floors to hide computers, electric lines, or connecting lines of electric appliances. Alternatively, an air-exhausting device is provided between the elevated floor and the ground to draw dust attached to the elevated floor. The currently available elevated floor in the market is manufactured by means of die-casting molten aluminum. As shown in FIG. 1, the die-casting process for aluminum alloy involves five steps including mold-opening, aluminum-melting, die-casting, forming, and burr-removing. During the aluminum-melting step, since high temperature and large amount of energy are necessary for melting aluminum ingots, energy is consumed greatly. As a result, using the elevated floor made of aluminum alloy becomes uneconomical and does not conform to the requirements for saving energy in the industry.

Consequently, because of the above limitation resulting from the technical design of prior art, the inventor strives via real world experience and academic research to develop the present invention, which can effectively improve the limitations described above.

SUMMARY OF THE INVENTION

The objective of the present invention is to provide a method for manufacturing a side-folded type elevated floor and a system thereof. Since the amount of energy necessary for manufacturing the elevated floor is not large, the usage of such an elevated floor becomes very economical and conforms to the requirements for saving energy in the industry.

To achieve the above-mentioned objective, the present invention provides a method for manufacturing a side-folded type elevated floor, which includes the steps of: providing a steel plate and defining positions of shearing lines and bending lines of the steel plate; shearing the steel plate along the shearing lines; stamping the steel plate along the bending lines of the steel plate to form a steel panel and a plurality of steel folds that are bendingly connected around the steel panel; and fixing the adjacent steel folds to form an accommodating region below the steel panel; thereby the side-folded type elevated floor is formed.

The present invention further provides a side-folded type elevated floor system, which is erected from the ground. The side-folded type elevated floor system includes a plurality of side-folded type elevated floor. Each side-folded elevated floor comprises a steel panel and a plurality of stamped steel folds. The steel folds of each side-folded elevated floor are bendingly connected around each steel panel. Further, the adjacent steel folds of each side-folded elevated floor are fixed to each other to form an accommodating region below each of the steel panels.

The present invention has advantageous features as follows. Manufacturing a steel elevated floor by a press-forming process consumes less amount of energy than that in the conventional elevated floor of aluminum material, thereby conforms to the requirements for saving energy in the industry. Furthermore, in comparison with the method of the present invention, the procedure for manufacturing the conventional elevated floor of aluminum material has one more step (burr-removing) to produce accurate dimensions. Therefore, the manufacturing method of the present invention is simpler.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to FIGS. 2 to 5. The present invention is to provide a method for manufacturing a side-folded type elevated floor, which includes the steps of S101 to S104.

In the step S101, a square steel plate 1 is provided, and the positions of shearing lines 11 and bending lines 12 are defined (FIG. 3). In the present embodiment, there are four shearing lines 11 and four bending lines 12. Each of the bending lines 12 is separated from one side of the steel plate 1 by a distance respectively and these bending lines 12 are parallel to each other. One end of each shearing line 11 is connected to the intersection of the respective bending lines 12, while the other end is perpendicular to one side of the steel plate 1.

In the step S102, the steel plate 1 is sheared along the shearing lines 11.

In the step S103, the steel plate 1 is stamped along the bending lines 12, thereby forming a steel panel 13 and a plurality of steel folds 14 that are connected around the steel panel 13 (FIGS. 4 and 5). Each of the steel folds 14 is formed into an L shape.

In the step S104, the adjacent steel folds 14 are welded to form an accommodating region 15 below the steel plate 13, thereby forming a side-folded type elevated floor 16 that is shaped as a box.

In order to improve the supporting capability of the elevated floor, some enforcement or reinforcement structure may further be installed on the side-folded type elevated floor 16 so as to enhance its overall structure strength. As shown by FIG. 6, the neighboring location between every two steel folds 14 in the accommodating region 15 may respectively be welded with a reinforcement sheet 17. Or as shown by FIG. 7, the frame 2 can be assembled with or integrally formed with the bottom surface of the steel panel 13, wherein the frame 2 may be connected with a reinforcement rib 21. Therein the frame 2 may be integrally or independently connected to the bottom surface of the steel plate 13.

Please refer to FIGS. 8 to 10. The present invention further provides a side-folded type elevated floor system.

The side-folded type elevated floor system includes a plurality of side-folded type elevated floor 16, a plurality of supports 3, and a plurality of inclined braces 4. The stamped steel folds 14 of each side-folded type elevated floor 16 are connected vertically to the periphery of the each steel panel 13. The adjacent steel folds 14 of each side-folded type elevated floor 16 are welded to each other to form the accommodating region 15 below each of the steel plates 13 (FIG. 5).

Each of the supports 3 comprises a body 31, a cap 32, a supporting seat 33, and a bottom plate 34. The cap 32 is fixed to the upper end of the body 31. The bottom of the supporting seat 33 is fixedly provided with a screw rood 35. The screw rod 35 is threadedly connected in the cap 32. The bottom plate 34 is fixed to the lower end of the body 31. The bottom plate 34 is threadedly connected to the ground. The edges of each supporting base 33 extend horizontally to form a plurality of first connecting portions 331. The first connecting portions 331 are fixed to the steel folds 14 via screws or welding (not shown). In this way, each side-folded type elevated floor 16 forms four supporting points via four supports 3. The edges of each supporting seat 33 extend downwards and obliquely to form a plurality of second connecting portions 332. The second connecting portions 332 are fixed to the upper end of the inclined braces 4 via screws. The lower ends of the inclined braces 4 are fixed to the ground via screws.

Users may further connect the frame 2 to the bottom surface of the steel panel 13. The interior of the frame 2 may further be connected with a plurality of reinforcement ribs 21. The frame 2 can be assembled with (i.e. independently) or integrally formed with the bottom surface of the steel panel 13. The reinforcement ribs 21 may crisscross or obliquely interlace in the frame 2. The region in which the frame 2 and the reinforcement ribs 21 are provided is a high load region of the elevated floor. The high load region allows heavier stationary machines to be put thereon. The rest region in which the frame 2 and the reinforcement ribs 21 are not provided can only support less weight than the high load region, so that it is used as a passageway for pedestrians or movable machines.

Furthermore, the top surface of the steel panel 13 may be provided with patterns or veins. There, the other surface of this patterned or veined region will have the frame 2 and reinforcement ribs 21. Via this arrangement, an operator can recognize the location of the high load region easily and clearly, thereby facilitating the arrangement of machines and passageways in a factory.

Please refer to FIG. 11. The present invention has a further important feature. If the user demands the side-folded type elevated floor 16 to have larger supporting capability, the user can provide at least one supporting post 5 in the accommodating region 15 of each side-folded type elevated floor 16. The supporting posts 5 are accommodated in the accommodating regions 15 and abut the bottom of the steel panels 13, thereby generating the fifth, sixth, seventh, or more supporting points in the side-folded type elevated floor 16.

According to the present invention, the method for manufacturing a side-folded type elevated floor and a system thereof have advantageous features as follows:

(I) With regard to the conventional elevated floor made of aluminum, since the aluminum alloy has poor flexibility, the stamping process is not feasible to manufacture the aluminum elevated floor. Thus, only die-casting the molten aluminum is practicable. However, manufacturing a steel elevated floor by the stamping process consumes smaller amount of energy than that in manufacturing the conventional elevated floor of aluminum material, which conforms to the requirements for saving energy in the industry.

(II) In comparison with the present method, the procedure for manufacturing the conventional elevated floor of aluminum material has one more step (burr-removing) to make the dimensions accurate. Thus, the manufacturing method of the present invention is simpler.

(III) At least one supporting post 5 can be provided in the accommodating region 15 of each side-folded type elevated floor 16, so that the load capability of the side-folded type elevated floor 16 can be increased.

The above-mentioned descriptions represent merely the preferred embodiment of the present invention, without any intention to limit the scope of the present invention thereto.
